Floor pounding bass!
Tight clean sounding bass with no distortion.
The speaker is large and heavy.
The Bottom Line:
If you have a house (not an apartment, condo, or townhome), pick up this subwoofer now! Make sure you test levels both inside AND outside your home.
Wow, I can't believe I waited this long to get back into upgrading my home theater. I was previously using a Sony 100 watt 8" subwoofer which I bought for my old apartment so I wouldn't drive the neighbors crazy. This speaker is so loud that I actually turned down the subwoofer gain to 0 on my receiver so I wouldn't bother my neighbors near my house (they didn't complain, I did it out of courtesy based on what I could hear from outside the house).
I am extremely pleased with the way this speaker handles low frequency sounds in both music and movies. While it only goes down to 50Hz (someday I'll hopefully have a subwoofer that can do 20Hz, almost the flutter sound), for most movies it will definitely bring out more of the action. After carefully positioning the speaker in the left corner of my room, I played some drum and bass followed by Pirates of the Caribbean. The bass from this speaker is extremely tight and it's so easy to setup I had sound coming out of it as soon as it was plugged in. I am using a monster subwoofer cable with the switch set to LFE, the cross over at the highest frequency and the gain on the speaker at the maximum setting.
The only con is the speaker is extremely large and heavy. But what did you expect for a 12" woofer in an enclosure with an amplifier? I can't wait to watch movies/TV, play video games, and listen to more music on this bad boy!
With my old 8" woofer, I heard the bass. With the Infinity PS-12, I feel the bass. For a 1550 sq ft house, this is plenty of bass! If I had a larger house, I could see the need for a larger or two subwoofer setup.
